Plot a line chart with conditional colors depending on values

Question

I want to plot a line chart. Depending on values it should change its color. What I found is:

plot(sin(seq(from=1, to=10,by=0.1)),type=\"p\", 
       col=ife         


        

Answer 1

Here is a little different approach:

x <- seq(from=1, to=10, by=0.1)
plot(x,sin(x), col='red', type='l')
clip(1,10,-1,.5)
lines(x,sin(x), col='yellow', type='l')

Note that with this method the curve changes colors at exactly 0.5.
